Window and door joints: 666 and 995
For joints between frames and walls, or suitable glass and frame joints, start with 666 and 995. Both are positioned here for non-structural window and door sealing. Discuss 666 for routine window projects and 995 when your project has additional sealing requirements or needs technical evidence for selection. Do not substitute these products for curtain-wall structural bonding.
Curtain-wall weathersealing: 5000
For weathersealing joints between glass panels or suitable aluminum panels, discuss 5000. Its role in this selection guide is joint weathersealing. Tell us the panel materials, surface finishes, joint location and exposure conditions.
Curtain-wall structural bonding: 9000
If the proposed bond has a structural function, discuss 9000 with the technical team before specifying a product. Share the system design, actual substrates, surface finishes and required test evidence. Structural bonding and weathersealing are different joint functions; project-specific suitability must be reviewed.

Clear interior finishing: M50
M50 is a one-component clear neutral silicone for non-structural interior finishing and suitable bathroom-fixture joints. Share the actual surface materials and joint location. The supplied instructions exclude concrete, marble, coated glass, copper and zinc; do not assume that every stone countertop is suitable.
Acid-cure glass sealing: 328
328 is a one-component acid-cure silicone for suitable non-structural glass joints. Review the glass type, any coating, and adjacent materials before selection. Aquarium suitability, structural-glazing use and a specific service-life promise are not established by this guide.

Common buying questions
Can I choose only by the product number? Use the model as an inquiry starting point. Joint function, substrates and project requirements determine suitability.
Can you discuss customized packaging? Send your packaging, labeling and quantity requirements. The available scope, minimum quantity and lead time are confirmed in the quotation.
Can you provide technical information? Ask for the available product data, safety information and relevant report for the selected product. Confirm that the document matches the supplied product version and intended market.
