Safety data

Review both SDS before handling. The A-Side contains MDI isocyanate and can cause respiratory and skin sensitization: use a supplied-air respirator when spraying, chemical goggles, chemical-resistant gloves and full skin coverage. Foam must be separated from the interior by an approved thermal barrier.
