Detailed Product Description

Description

ZJ-701 fireproofing Silicone Sealant is a one-part, neutral curing ,fire-rated silicone sealant. It has an excellent adhesive ability to most construction materials without a primer.

Characteristic

It has Good features as follow:

a. Can be easily used and extruded any time.

b. Excellent thixotropic and extrusion ability, in any air temperature( -40 to 100) can extrude easily.

c. Neutral cure, no corrosive to most structural materials.

d. When meet flame, it will not help to burn.

Where to use

It has excellent unprimed adhesion to a range of common construction substrates including stone,steel masonry,brick,wood,etc. It is ideal for weather-sealing of curtain walling, building facades and expansion joints where a fire rating is required. It is also suitable for use in penetration sealing systems where pipes and cables pass throug fire rated structures.

Construction project technology service

It's needed to take the design, choose materials, operation into consideration for the structural joint sealing. The technical communication between suppliers and applicants are necessary for the present situation: varied sealant types, daily changing materials and the compatibilities between surface treatment and materials. Hangzhou Zhijiang Silicone Chemicals Co., Ltd. gives construction project technical services as follows:

Adhesion Testing

ZHIJIANG Silicone will evaluate tests about the adhesion of our products to job site or representative job site materials in standard laboratory. Results of the adhesion testing, product recommendations and surface preparation will be forwarded in writing.

Compatibility Testing

Incompatibility of glazing materials can lead to sealant discoloration and/or loss of adhesion. To help protect against these problems and to ensure compatibility, ZHIJIANG will also test and provide information on the compatibility of accessory materials (gaskets, spacers, etc.) and other ZHIJIANG Silicone sealants.

Stain Testing

Because of the staining problems that may occur with porous substrates, ZHIJIANG is willing to run laboratory tests and provide information to you on the possibility of staining occurring with the construction materials being used.
