the 8:1 and 16:1 mixing ratio's, is that by volume or weight?

can u use the catalyst hardener in acrylic enamel

Asked by: TALL
Majic Catalyst Hardener should not be used with acrylic enamels. Catalyst Hardeners react with hydroxyls found in alkyd resins – the reaction between hydroxyls and isocyanates form a urethane molecule that unites these hydroxyls into a harder, stronger, more continuous film. These hydroxyls are not found in acrylic resin chains, so the catalyst hardener has nothing to react with. If a catalyst hardener were added to a solvent borne acrylic coating, it probably would not cause any functional, or performance, issues – but no benefit would be realized by doing so… The reactive component of a catalyst hardener is isocyantes, which will react with moisture (humidity) if a hydroxyl is not present. So, from strictly an aesthetics perspective, If moisture, in the form of humidity, is pulled into the finish to react with the isocyanates, the most common result is an indelible “blush” will form into the film, causing the finish to look hazy, and faded. Simple answer – Not recommended. But this explanation also pertains to “over-catalyzing” a product that will react with a Catalyst Hardener (such as Majic Tractor & Implement Enamel). Using too much catalyst may result with the same effect as described above.

If you brush on paint should you use hardener and if so how much.

Asked by: gjll
Majic Catalyst Hardener is an optional additive to Majic Tractor, Truck & Implement Enamels to increase hardness, and accelerate curing of the finish enamel. If you decide to use Majic Catalyst Hardener, #8-0950, the mix ratio will be the same for brush, roll or spray application. Always mix Majic Catalyst into Majic Tractor & Implement Enamel at a rate of 16:1 (16 parts T&I Enamel to 1 part Catalyst Hardener). Be sure to read and follow package directions carefully pertaining to Mixing, Safety & Disposal. Once mixed, allow product to stand, undisturbed, for 20-30 minutes before application... Only convert that which can be applied within an 8 hour period of time – after 8 hours, any un-used catalyzed enamel should be discarded. Majic Catalyst Hardener is designed, and recommended, for mixing into Majic Tractor & Implement Enamels – not for use with primers, nor with the optional Clear Coat High Gloss Lacquer. For brush application, we will still recommend thinning product between 5-10% with Majic Reducer. The reason for this is two-fold…(1) Majic T&I enamels are VOC compliant, high solids coatings that, when applied full-bodied, may sometimes “drag” and not level all that well (especially if humidity is high) – the addition of Majic Reducer allows the product to remain VOC compliant, but aids in the flow & leveling of the applied film…. (2) Again, due to the high solids content, brushing can easily be applied too heavy – reduction helps to keep the application to within the recommended applied thickness of 2.5 mils wet. Please remember that, whether brushing – or spraying, the product needs to be applied in very thin coats (recommended 2.5 mils wet), and allow a full 24 hours (minimum) to dry between coats. Too heavy an application, and/or re-coating too soon may result in a film that won’t dry “hard” for several days…or longer.

What ratio do I use with the paint and how much reducer the use? Can I use lacquer thinner as a reducer ? Thanks

Asked by: Mark1234
Majic Tractor & Implement Enamels and Primers are heavy duty industrial oil/alkyd products, and are packaged VOC compliant - nationwide. Majic Reducer, #8-0750, is a proprietary blend of “exempt” solvents, and mixes perfectly with the solvent structure of Tractor & Implement products – because the solvents in Majic Reducer are “exempt” – they add 0 VOC to the host product, keeping the product legal, and environmentally responsible. For spray application, an 8:1 ratio is recommended (8 parts Majic T&I Product to 1 part Majic Reducer). This is a “plus-or-minus” ratio as the spray equipment used, the atmospheric conditions at time of application, and the end-users personal preferences, will determine the actual ratio. The proper ratio will result in a fine, continual atomization of product, and allows for best “flow & leveling” of the applied film. As already mentioned, the reduction ratio may change – daily – based on the atmospheric conditions at time of application. Adding more solvent than the recommended 8:1 ratio will not hurt the product – but may result in a diminished gloss. Adding less solvent than recommended, may result in a slight “orange-peel” texture. Never reduce with Lacquer Thinner – Lacquer thinner will turn the product to a gel (making it near impossible to spray, and clean-up), PLUS, lacquer thinner will attack and dissolve the resin, so that if it were able to be applied, much of the film’s protective properties would be severely compromised. Regarding Majic Catalyst Hardener, #8-950: Majic Catalyst Hardener is not the same as reducer, but may be used, in conjunction, with Majic Reducer. Majic Catalyst Hardener strengthens the paint film (increasing abrasion resistance) and accelerates the film’s overall cure time (allows the product film to reach maximum hardness faster). The mix ratio for Majic Catalyst Hardener is 16:1 (16 parts Majic T&I Enamel to 1 part Majic Catalyst Hardener). This is NOT a plus-or-minus ratio. Do not exceed the 16:1 ratio as it will not create a greater hardness, and may result in an indelible “blush” to the finish. Majic Catalyst Hardener is designed for use with Majic Tractor & Implement Enamels, and is not recommended for use with Primers nor Clear Coat. When mixing Majic Catalyst Hardener, always follow safety, mix an disposal instructions carefully. Do not catalyze more product than can be applied within 8 hours and discard any unused product after 8 hours.

Will this cause a low gloss paint to gloss?

Asked by: TSCquestion
This is a great question, manufacturers will often claim that the use of their Catalyst Hardener will incrementally increase the gloss of the host product…and this is true (sort of…). What happens is a catalyst-hardener will join loose strands of an alkyd resin chain to form a harder, more continual film. By doing so, some of the microscopic texture & “pinholes” (or voids) of an applied alkyd film will be minimized, if not eliminated. This will give the reflective value of a higher gloss – BUT, the measurable gloss increase is less than 10%, and is not discernible to the human eye (for example, Majic T&I Matte Black has a gloss rating of 0-10, out of 100, on a 60° gloss meter – a 10% gloss increase would be <1 unit). The answer to your question is, “No, a low-gloss (matte) finish will still be a low-gloss (matte) finish. What the Catalyst Hardener will do is increase the measurable film hardness by as much as 30% - which contributes to greater abrasion resistance & slightly better chemical resistance – and accelerates the film “curing” by up to 40% - which means it reaches it’s max level of hardness sooner, than if no catalyst hardener were to be added. Having said all this, Majic Tractor, Truck & Implement Enamels are very hard drying oil/alkyd enamels, and the use of a post-add Catalyst Hardener is completely optional. Majic Catalyst Hardener is NOT recommended for use with Majic T&I Primers, nor Majic Clear Coat High Gloss Lacquer – only for use with Majic T&I finish enamels. Please make sure to read and follow all safety, mixing and disposal directions printed on the product label and Product Data Sheet… Also, please be aware that Majic T&I Products still need to be applied in thin coats, and to allow a full 24 hours dry time between coats (with, or without the use of Majic Catalyst Hardener).

Would you still use a clear coat if catalyst hardener is used?  Are there any specific pros or cons using a clear coat if catalyst hardener is used? 

Asked by: Thoran8888
Majic Catalyst Hardener, will increase the hardness of Majic Tractor & Implement Enamels by up to 30% (increasing abrasion resistance), and accelerate the film’s “cure” time by up to 40%. Majic Catalyst Hardener is an optional addition to the product, and is intended for the final application(s) of Majic Tractor & Implement Enamel finishes. In contrast, Majic Clear Coat is an acrylic modified alkyd coating designed to give greater and deeper gloss to the enamel finish, and to protect the enamel finish from the damaging affects of UV light (color fade and loss-of-gloss) – Allow the final coat of enamel to “cure” for 10-14 days prior to application of Clear Coat, do NOT mix Majic Catalyst Hardener into Clear Coat.

I just want to clarify... if I want to mix one complete gallon of paint (Majic tractor enamel) with reducer & hardener is this a correct ratio... 1 gallon of paint + 1/2 pint hardener + 1 pint reducer?

Asked by: Blake B
Yes, that is the correct ratio for the mixture.

Is this an aliphatic isocyanate? Does it contain any aromatic isocyanates? Will it cause an alkyd to loose gloss and or chalk when exposed to UV?

Asked by: 432rover
Majic Catalyst Hardener is an aromatic isocyanate catalyst, and will not cause the finish to lose gloss, fade, or chalk. The primary functions of a catalyst/hardener are to (a) increase hardness, (b) accelerate cure time, and (c) increase gloss level of a finish product...in most instances, the hardener will work - to a degree - to stave off the damaging effects of UV light to an alkyd resin. There are, however, many other factors that will have a greater impact to what you have described as the "loss of gloss" and "chalking" of an oil/alkyd resin found in Majic Tractor & Implement Enamels, than will the use of a catalyst hardener. These factors include, but certainly not limited to, methods of application, reduction ratios, types of reducers used, applied thickness, recoat times, atmospheric conditions at time of application, methods of surface preparation, types of primer used,care and maintenance of an applied coating during the very critical "cure" time (60+ days following application), etc...
