Additive
The main additive is Gplus polymerization inhibitor. It is a classic phenolic polymerization inhibitor with white to light yellow crystals. All types of organic solvents and monomers have extremely high solubility. Added to each polymer formula to maintain thermal storage stability and effectively inhibit viscosity increase, but does not affect photopolymerization efficiency. It is light in color, does not turn yellow when cured, is safe and environmentally friendly, has no irritating odor or migration and release of harmful substances, and can be used in medical and health care and food packaging products.

do you have any question?

Are there any products that can improve thermal storage stability?
Glpus polymerization inhibitor It is a classic phenolic polymerization inhibitor, white to light yellow crystals. The monomer has extremely high solubility in various organic solvents. It is added to various polymer formulas to maintain thermal storage stability and effectively inhibit viscosity increase, but does not affect the efficiency of photopolymerization. It is light in color, does not turn yellow after curing, is safe and environmentally friendly, has no irritating odor and releases harmful substances, and can be used in medical and health, food packaging products
What is a flat bottomed drill used for?
The cutting surfaces on a vertical end mill bit (are for milling ) are on its sides , designed for cutting horizontally , a drill bit ( are for drilling ) cutting surface is at its tip , designed for cutting vertically downward .. you'll notice a end mill usually has a flat on the end of the bit .
If I want to increase the impact strength, what should I choose?
AMK-75 titanate crosslinker can crosslink with active groups such as hydroxyl and carboxyl in substrates, inks and coatings to form bridges, increase molecular weight, and thus improve heat resistance, chemical resistance, water resistance, dryness and many other properties. The bridging effect of the titanate between the resin and the substrate ultimately improves the adhesion of the ink and coating.
What products can improve adhesion?
MP-397 isocyanate silane coupling agent is used as a crosslinking agent and adhesion promoter in coatings, inks, and adhesives. Its outstanding wet adhesion properties make it widely used on glass, metal, and other inorganic substrates; it can also adhere well to organic materials that are difficult to adhere to, such as nylon and other plastic products. It can hydrolyze quickly in the presence of atmospheric humidity, does not turn yellow, and has very good thermal stability, chemical stability, and UV stability. Suitable polymers: acrylic, silicone resin (Si), PU-prepolymer, etc.
Characteristics of additives
Adjuvants are auxiliary materials used in specific fields. They generally have no biological activity themselves, but are indispensable additives in dosage form formulation or application. Adjuvants have a wide range of applications, including but not limited to the processing and application of pesticides, adhesives, plastics and other fields.
Improve storage stability
Gplus inhibitor can maintain thermal storage stability and effectively inhibit viscosity increase without affecting the photopolymerization rate
Improve product performance
