1. Recommended main resin
1.1 Sealing resin
Trust-7136B trifunctional polyurethane acrylate, the fastest curing, high hardness, good alcohol resistance. Suitable for low energy curing with 405nm or 395nnm light source, used as main resin with thiol curing agent, or with methoxy monomers can be used in mercapto-free sealant, achieving 60 seconds fast curing. The coating is dry, tough, full of gloss, and excellent storage stability.
Trust-7135 is a two-functional polyurethane acrylate with fast curing, good toughness, pure color and no yellowing. When used with a mercaptan curing agent, it can be cured in 60 seconds under a 405nm light source with low energy. When used with a methoxy monomer, it can be cured in 60 seconds under a 395nm light source. It has low heat release, small volume shrinkage, low odor, and a tough coating. It is the best choice for sealing resin.
1.2 Middle coating color glue resin
Trust 7081 is a two-functional polyurethane acrylate with moderate curing speed, good pigment wetting and excellent intercoat adhesion. It is suitable for color-adding midcoat.
1.3 Primer resin
Trust-7005 is a two-functional polyurethane acrylate, with flexible coating, small curing shrinkage and good adhesion. It has the purest resin color and odor.
1.4 One-step color glue resin
Trust-7089 is a two-functional polyurethane acrylate with fast curing and excellent adhesion, and good color development. It can be used in transparent sealing layer and color-added one-step glue application. It is suitable for long-wave low-energy light source curing.
2. Single-body recommendation
2.1 Sealing layer application
AM-318 monomer ACMO acrylic morpholine, the advantages are fast curing and high hardness, the disadvantage is that it has a little yellowing during curing, especially in white system, the monomer is water-soluble.
FM-362 methoxyacrylate monomer has the advantages of obvious antioxidant and polymerization inhibition effect, good surface drying, low viscosity and strong dilution ability. The disadvantage is that the price is relatively high.
Three: Additive Recommendation
3.1
Thiol curing agent Thiol-45L has high purity, low odor, and stable storage. Thiol-30L has high purity, good antioxidant and inhibition effect, and high cost performance.
3.2
AD-2001 heat stabilizer, no yellowing, enhances the thermal storage stability of nail polish, does not reduce the speed of light curing reaction.
3.3
AD-2003 Inhibitor, suitable for use in color glue systems, in the presence of a large amount of long-wave photoinitiators in the formula, to improve light storage stability. Slight yellowing occurs when the temperature is too high, and it is not recommended for topcoat.
