Caulking 101. Talking to a caulking Chemist!
What happens here
Rob details the four primary components of caulk: first, the 'Emulsion Polymer,' which acts as the 'glue' providing most of the desired properties like elasticity, adhesion, and water resistance; second, 'Types of Fillers' such as calcium carbonate, used to make the product tougher, stronger, and to minimize shrinkage; third, 'Mildewcides' to ensure the product is mold and mildew resistant; and fourth, 'Surfactants' or 'Soaps' that stabilize the entire system. He also notes that the type of polymer selected (e.g., all acrylics vs. vinyl acrylics) significantly influences the product's performance and can be modified with other raw materials like styrene for water resistance.
Goal: Identify and understand the function of the four main chemical components in caulk.
Tools and materials
- All Acrylics N/A — A type of polymer considered to be a better quality product
- Calcium Carbonate N/A — A type of filler to increase toughness, strength, and minimize shrinkage
- Emulsion Polymer N/A — Providing elasticity, adhesion, and water resistance; the 'glue' of the caulk
- Mildewcides N/A — Making the caulk mold and mildew resistant
- Styrene N/A — Modifying polymer for enhanced water resistance
- Surfactants N/A — Stabilizing the caulk system
- Vinyl Acrylics N/A — A type of polymer with different performance characteristics
