7. Technology Service
l We supply integrate data, technical consultation and free compatibility test.
l Solving problem in the course of using timely
l Pollution Test:
Attention: Girafe 958 Silicone Stone Sealant will not cause any pollution and adhesion to most stone materials. However, different stone materials from different places contain different chemical component and crystalloid structure, even stone materials are porous substance. Some chemical processing auxiliary will be left on the surface of stone or porosities of stone when processing. So we are not sure whether the product is suitable for all cases, it may cause pollution in some case. We suggest customers to send the substrate to us before using; We will provide pollution test for you. And we will submit the test report and recommend application method.
8. Joint Design and Operation Procedure
l Please see “Operation Instruction to Girafe Silicone Sealant ”
9. Safety
l Silicone sealant will release volatile compound so that it could be harmful to health, therefore, please keep good and ventilate;
l Silicone sealant will not release any harmful substance and not be harmful to health after cured;
l Keep uncured silicone sealant beyond children’s reach. If getting into eyes, wash off with running water and consult a doctor;
10. Warranty
l As an ISO9001,ISO14001 certified company, we are committed to establish and implement the ISO9001 Quality Management System.
l We will sign the Quality Guarantee with customers after they buy our products and confirm the construction organization and engineering.
11. Maintenance
l Generally there is no need to repair. If the seal joint is damaged, please remove the damaged silicone sealant, clean the surface of substrates, and fill up with silicone sealant.
l Girafe silicone sealants have good adhesion to cured sealant.
