Usage:
Plastic
The Monomers can be added to cured coating formulations to form flexible yet rigid plastic films. The addition of radiation medical formulas can improve the elongation rate, viscosity and viscosity of high-gloss and low-gloss coatings
, wood
enhance product performance, increase productivity and reduce pressure on environmental pollution. It is an ideal choice for scattering coatings in the furniture industry. The main reasons for its use need to be investigated. The addition of UV-resistant coatings used in the wood flooring industry can provide equivalent physical properties to wax-free flooring.
, Papermaking
B and B curing coatings used in papermaking or cardboard generally require lower viscosity and high reactivity. These standards are met by improving flow and gauge levels while maintaining good curing properties.
, Metal
Coatings for metals generally use cationic vinyl ether/epoxy chemistry or heterocyclic systems to form formulas. The function is to cross-link with vinyl ether or acrylic functional groups to form an excellent activity in these systems. of diluent.
.>, Ink
The packaging market uses B and UV curing technologies to speed up production and reduce energy consumption. Curing inks with excellent performance and low odor occupy an important share of the screen ink market.
, Electronics
Electrical equipment manufacturers rely on rapid processing and low-temperature processing of coatings to protect cables and electrical components as well as printed circuit boards.
, Adhesives
Strict emission requirements and the need for higher cure rates have prompted the industry to develop a wide range of cured adhesives.
Packaging, storage and transportation:
Kilogram/plastic drum, sealed, protected from light, low temperature, neutral or weakly alkaline conditions. When storing and handling, pack and unload with care to keep the packaging intact and prevent leakage. It can semi-polymerize when shaken, stored for too long or exposed to light, so it should be distilled before use to prevent polymerization.
Remarks:
&Soluble in water, methanol, ethyl acetate, ethanol, methylene chloride, hydrocarbons (hydrocarbons)
& Sealed, protected from light, low temperature, neutral or weak base Stored under non-toxic conditions
& Poisonous, slightly odorous, corrosive to rubber and leather, do not splash into eyes or contact with skin
& Can semi-polymerize when shaken, stored for too long or exposed to light. Therefore, it should be distilled before use to prevent polymerization.
