[RHEOBYK-7691] Preservative and VOC-free associative thickener

[RHEOBYK-7691] Water-based solid, non-dusting preservative and VOC-free associative thickener.

Features RHEOBYK-7691 has an extremely low impact on low shear regions while increasing viscosity in high shear regions. [In the field of coatings] • The following properties are improved: - Workability - Leveling properties - Storage stability - Abrasion resistance • Reduces splatter during application • Achieves a high film thickness while maintaining an excellent balance of fluidity and leveling • Does not adversely affect gloss and color acceptance • Supplied in flake form to prevent dust generation and enhance application safety • There is no need to add preservatives to the additives to prevent microbial intrusion
