Product introduction

Content: 26-28


Product appearance: white to light yellow milky liquid


Product Name: Water-based leather foaming agent, polyurethane foam stabilizer.


Product performance and application:

This product is an aqueous solution of non-ionic surfactants, commonly used in the mechanical foaming of water-based leather foaming agents foaming stable agent and water-based polyurethane resins (PUD). As a high-efficiency foaming aid, it can form very fine and uniform cells and maintain the high stability of the foam, making the artificial leather or polyurethane coating soft after heating and curing.This is a Leather Coating Product.

It is a very efficient foaming aid with fast foaming speed and high efficiency. It can reach a foam density as low as 200 g/l (about five times the foaming ratio). It can help to achieve a very fine and uniform cell structure, and the foam has extremely high stability. The recommended dosage of the product is 2-8% (per 100 parts of PUD), and the actual dosage depends on the type of water-based resin and the specific formula. It is recommended to add MJ-EP77 before mechanical foaming. Depending on the actual dosage, it has a certain thickening effect on the foam, so it can reduce or even not use thickeners to achieve the desired viscosity range.It is Environmental Odorless Water Based Foaming Stable Agent For Pu Leather Coating.


It can help to form a very stable foam layer and can withstand more severe process conditions, especially when the product is less prone to surface defects such as cracks at higher drying temperatures, so it can significantly shorten processing time and improve production efficiency.

It is suitable for a wide range of pH and salinity, and the use effect is not affected by water hardness. Because the product contains hydroxyl groups, if the formula system contains curing agent, it can react with it, and it can be closely combined with the polyurethane foam layer after high temperature curing, and it is not easy to migrate in the later stage.


Product packaging specifications: 180KG; 1000L of Square slot         


The Shelf life:

The shelf life of the sealed package at room temperature is one year.
