Sealant Chemistries. Joint Sealants can be broken down into six primary categories: 1. Acrylics (solvent-based) Paint. Used in residential and light commercial construction, mainly for exterior applications. 2. Butyls (solvent-based) Some are non-hardening and are suitable for concealed application where sealant needs to remain pliable. 3.

Applications of Biopolymers in Construction …
Dispersing effects are typically achieved by chemically modified, anionic polymers with rather low molecular weight (e.g., lignosulfonates). Some biopolymers have surface-active properties (e.g., protein extracts) and are efficient air-entraining agents for concrete or mortar, while others containing carboxylic groups (e.g., polyaspartic acid) are powerful set retarders for gypsum and cement.
