MOQ, Lead Time & Private Label — PR-111
FAQs — PR-111
What is PR-111 used for?
Exterior window and door perimeter sealing, general construction and expansion joints, metal and glass facade weatherproofing, and concrete and masonry joint sealing.
What is the difference between PR-111 and PR-666?
Both are neutral cure weatherproof sealants: PR-111 is qualified to JC/T 485-2007 and PR-666 to GB/T 14683-2017. PR-111 is the general-purpose grade with a high extrusion rate for fast, labour-saving application. PR-666 is the higher-specification all-weather grade with a 516 mL/min extrusion rate and 0.6 MPa modulus.
What standard does PR-111 meet?
JC/T 485-2007 (window and door elastic sealant, classification SR 3 MG AK). Test report 2025ME159 is available on request.
Can it be used for structural bonding?
No. It is a weatherseal product and should not be used where the sealant has to carry load. Use PR-999 for structural applications.
What is the MOQ and lead time?
Standard OEM and private label MOQ is 1,000 pcs per model, with mixed-model trial orders from 3,000 pcs total and stock items from 500 pcs. Typical lead time is 15–25 days after artwork and sample approval.
