AAEM(Acetoacetoxyethyl Methacrylate) is one of the most important products ,designed to improve the performance of acrylic polymers in coatings and adhesives. Especially for the requirements to improve adhesion, reduce glass transition temperature (can improve the elasticity and toughness of the coating), reduce the viscosity of the system (especially for high solid content system) and improve the cross-linking density has a very good effect. It also improves the adhesion of coatings to metal, ore and wood surfaces.
Compared to the solvent system, the water-based system provides us with a more environmentally friendly and healthy alternative. However, water is more difficult to fully evaporate from the system than other organic solvents. Therefore, water-based systems reduce the drying time of the coating by increasing the solid content as much as possible. Unfortunately, most high solids systems also have very high viscosity, which makes it very difficult to operate. The addition of AAEM reduces the viscosity of the acrylic polymer system, allowing the builder to easily use a water-based system with zero solvent volatilization.
The addition of AAEM helped improve the durability and toughness of water-based polymers, which, when cured at room temperature, tend to have intrinsic performance deficiencies compared to solvent systems, such as durability and toughness, and significantly improved scratch resistance and dust adhesion.
Q1: May I get one sample before placing order?
Re: Yes, Sample are available. For normal products, samples are for free and you just need to bear the freight;
For those high value products, you just need to freight and certain product cost. When we both cooperate for
some times or when you are our VIP customer, free sample will be offered when you need.
Q2: Which payment is available for your company?
Re: T/T, L/C. You can choose the one which is convenient for you.
Q3: How and when can I get my goods after payment?
Re: For small quantity products, they will be delivered to you by international courier(DHL, FedEx, TNT etc.)
or by air. Usually it will cost 3-5days that you can get the goods after delivery.For large quantity products,
shipping by see is worthwhile.It will cost days to weeks to come to your destination port, which depends on
where the port is.
Q4: Is there any possible to use my appointed label or package?
Re: Yes. If needed, we'd like to use label or package according to your requirement.
Q5: How can you guarantee the goods you offer is qualified?
Re: We always believe honesty and responsibility are basis of one company, so whatever products we provide
for you all are qualified. We will have goods tested and provide COA before delivery for sure.
