When building, adhesives are often overlooked and considered at the last minute. However, adhesives are often more toxic than the flooring and other products they are made to adhere.
Most adhesives are still based on SB latex, which releases large quantities of toxic volatile organic compounds (VOCs). The volatile solvents are used to emulsify (or liquefy) the resin that acts as the bonding agent.
However, water-based adhesives emit far less VOCs than their conventional solvent based counterparts.
