Description
SMA-20H is a functionalized polymer containing maleic anhydride groups produced through a new reactor polymerization method Polymer. Because it has high reactive active groups and can react with different groups, such as carboxyl and amino groups, it can improve the uniformity of different substrates Scattering effect, excellent compatibility, and improving the comprehensive performance of the material.

Application
Due to the unique structure of the product, SMA-20H is mainly used in the following pathways and areas that have not yet been developed.
Mainly used in ink coating series products:
1,Pigment dispersant
2,Ink viscosity stabilizer
3,High heat resistant finishing paint
4,Leather retanning agent
5, Paraffin wax, rosin lotion dispersant
6,Paper sizing agent
7, Recycled nylon chain extender
8, Cleaning agent
9, Epoxy curing agent, matting agent
10,Copper clad board
During the hydrolysis process of SMA-20H in pigment dispersion, the SMA resin opens its ring to form two adjacent carboxylic acid groups, which can form various forms of ionic polymers.
Hydrolyzed SMA resin can be used as a reactive polymer surfactant for pigment dispersion. SMA resin is suitable for pigment wetting, grinding, and dispersion in water-based ink coatings.
The excellent properties of SMA resin make it more suitable for preparing stable water-based pigment dispersion systems with high color to base ratio and high pigment content than styrene acrylate polymers.
SMA-20H can be used as an alkali soluble resin in water-based ink and water-based varnish applications, with a typical addition of 5-10% (resin dry weight ratio) to replace styrene acrylic solid resin,It can significantly improve the water resistance, heat resistance, and adhesion to polar substrates of the film, while maintaining a high gloss.Even if a 1% addition is sufficient to observe a change in performance, up to 20% addition will not have a negative impact on film formation.
SMA-20H can be added as a polymeric surfactant or alkali soluble resin in the dairy industry,
Comprehensively adjust the particle size of lotion, improve the stability, heat resistance and water resistance of lotion, and endow lotion with ideal comprehensive properties.
Advantages of SMA-20H in leather retanning agents:
1. Good wettability to pigments;
2. Good permeability to fatliquors;
3. The anchoring effect of chromium ions on wet blue skin is very obvious, allowing free chromium particles to fill the interior of the fiber.
