Controlled air blowing generally raises the softening point and lowers penetration. This harder industrial binder is selected around service temperature, substrate and the finished-product specification. Check both softening point and penetration when comparing grades, alongside the intended manufacturing or installation process. For an enquiry, describe the finished application and any required handling or packaging conditions.
Reference limits from the SRNT catalogue, not measured batch results or a COA. Availability, the applicable standard edition and contractual limits are confirmed for each enquiry.
