brief introduction

smp additive is a purified, nanometer modified and viscosity improved montmorillonite clay. it is off-white, soft, nonpoisonous and tasteless. because of excellent expansibility, gel dispersing ability, suspension, thickening and thixotropic performance, it can be used as anti-settling agent, latex stabilizer and rheology modifier in water based system. besides, it also has the property of good absorption, iron exchange and cohesive in water based system.

smp high purity nanoclay’s main chemicals are sio2 and al2o3. two layers of silicon-oxygen tetrahedron and one layer of aluminium octahedron lamellar stack to form montmorillonite clay particles. the thickness of single layer is 0.96mm. electronegativity exists between layers and they can exchange ions and get modification. .those layers have good thermal stability and help to reach excellent flame retardant and barrier propertity..

pre-gel usage: smp is slowly added to water with 25-35℃ temperature with constant mixing, increase the mix speed to 1500-2000rpm for 20-30min to avoid clumping and reach full dispersing. then place it for 8-12h for use. put this gel into the whole system with constant mixing until complete dispersing (pre-dispersing concentration of montmorillonite clay in water is 8-15%). using pregel has better performance than add powder directly.
