Ways to understand intumescent coating hardness
Language within some commercial intumescent coating specifications suggest that harder coatings are better. That isn't true. Truth aside, where one sits in the contract chain is a good indicator of how impactful they feel material hardness is to overall project success.
Shore D hardness is not a performance indicator for intumescent coatings
For decades, many intumescent coating specifications have ruled out the use of materials that measure less than 70 in Shore D durometer testing. Hardness is useful to know, but it has no influence at all on an intumescent coating’s performance in the event of a fire.
Shore D hardness doesn’t matter for intumescent coating performance
