AT THE SITE

 

This would include the adhesive used for the wood doors only if the doors were built on-site.  Products used at outside manufacturing facilities would not be subject to these limits.

Aerosol Adhesive
is an adhesive packaged as an aerosol product in which the spray mechanism is permanently housed in a non-refillable can designed for hand-held application wihtout the need for ancillary hoses or spray equipment.  Aerosol adhesives include spaceial purpose spray adhesives, mist spray adhesives and web spray adhesives.
Adhesive
is any substance that is used to bond one surface to another surface by attachment.  Adhesives include adhesive bonding primers, adhesive primers, adhesive primers for plastics and any other primer.
Indoor
applies to all materials that have the potential to emit contaminants to indoor spaces; typically all materials inside the exteior moisture barrier.
Porous Sealant
is a substance used as a sealant on porous materials.  Porous materials have tiny openings, often microscopic, in which fluids may be absorbed or discharged.  Such materials include, but are not limited to, wood, fabric, paper, corrugated paperboard and plastic foam.
Primer
is a material applied to a substrate to improve adhesion of subsequently applied adhesive.
Non-porous Sealant
is a substance used as a sealant on non-porous materials.  Non-porous materials do not have openings in which fluids may be absorbed or discharged.  Such materials include, but are not limited to, plastic and metal.
Sealant
