Product name:

OM904 Waterproof building Sealant

Product Introduction:

OM904 two-component waterproof building sealant is made of liquid polysulfide rubber as the main base material, adding a variety of chemical additives by special molecular material synthesis process. The product has excellent water resistance, oil resistance, aging resistance and corrosion resistance. It is famous for its good sealing performance, strong adhesion, good elasticity and long service life.

This product executes: JC/T483-2006 "polysulfide building sealant" ** building materials industry standard.

Scope of application:

Widely used in construction engineering, tunnel engineering, water supply and drainage engineering, water conservancy engineering, municipal construction engineering, highway Bridges and airport runway in all kinds of deformation joints, expansion joints waterproof seal.

This product belongs to the ** grade, specially made for water purification plant V type filter, filter plate seal.

Main technical indicators:

Construction guide:

0M904 two-component polysulfide building sealant, simple construction, easy to operate, but the operator must be in strict accordance with the operating rules of construction, in order to achieve full curing and good mechanical properties.

Primary treatment

The interface of the construction substrate should be carefully treated and cleaned, especially for floating ash or residual casserole, oil pollution and other pollutants. Conditions. Use air pump to wash clean. If the substrate interface is obviously wet must be dried.

Substrate material

Substrate material is used to fill too large or bottomless joints, so as not to waste sealant, while avoiding glue bonding on three sides, affecting the performance of the glue. The substrate material should be non-rigid honeycomb material, it is recommended to use polyethylene (PE) foam strip is preferable, the size should be 20-30% wider than the actual seam, the substrate material is under pressure after installation.

Protection of construction interface

In order to prevent rubber pollution around the construction, it is recommended to stick 50mm wide antifouling belt 10mm on both sides of the joint, pay attention to the end of the construction, that is, remove the antifouling belt.

Configuration of glue

Measure component A (base glue, white) and component B (curing agent, black) in a ratio of 10:1-1.2 (weight ratio), mix the two components in -, and stir at a slow speed for 5-8 minutes with a high power pistol until the reflected color is lost, then turn the side seam material to the center with a putty knife, and stir again. To blend evenly, the good material must be used up within 2 hours.

sizing

With putty scraper or glue gun will be configured in the joint interface coated with a layer of scraping, so that the interface is better infiltrated, and then embedded in the middle of the seam to the specified thickness after compaction, operation should avoid entraining bubbles, for special parts need higher bonding strength can use the company's matching bottom coating. Inspection should be carried out after the completion of construction, and timely repair should be done when there is a shortage of materials. After sizing, water flushing, rain or other damage should be avoided in **.

Matters needing attention

The closed water test should be performed seven days after sizing.
