## Questions & Answers

**Q: Does this provide abrasion resistance for acrylic or latex paint? I assume at less than 1% by weight, what does a gallon of this weigh?**
A: Hello This product will not enhance or create abrasion resistance.  This material is ideally designed to create thixotropic properties.  Weight per gallon is roughly 1 pound.  This material does tend to settle out during shipping.  Make sure to shake container before use and this will redisperse particulates..Thank you

**Q: Is this product comparable to smooth-on's thi vex silicone thickener?**
A: No, this is not a compound, it is sand.

**Q: will this product thicken polyester resin ?**
A: Yes.  And work excellent!

**Q: Two questions in one, actually, the can looks pinkish, is that the color of the powder? Can it be mixed with paint as a filler? Thanks**
A: The powder is white as snow.  This can be mixed with paint.
