Stable foaming agent for water borne leather

MJ-EP77
Product Description
MJ-EP77 is a highly efficient and stable foaming agent, commonly used in water borne polyurethane resins and water borne synthetic leather, to soften the artificial leather or polyurethane coating after curing.
Product Characteristics
Fast foaming speed with high efficiency, can reach as low as 200 g/ L foam density (about five times the foaming rate);
Fine, smooth and even foam with high stability;
It can withstand more stringent process conditions, especially in higher drying temperature, to make applied products not prone to cracking or produce other surface defects;
Adapted to a wide range of pH and salinity, and is not affected by water hardness;
Compared with other commercially available ionic foaming agent, MJ-EP77 has a higher molecular weight and significantly reduces the probability of migration in the finished product.
Typical Properties
Appearance: White to light yellow opaque paste
PH（1%, Aq.sol,20℃）：＞6
Product Application
The recommended dosage of the product is 2-8% (per 100 parts PUD), but it depends on the type of water borne resin and customer’s specific formulation.
It is recommended to add MJ-EP77 before mechanical foaming, which has a certain thickening effect on foam, so the ideal viscosity range can be achieved by reducing or even without using thickening agent.
