Product Introduction

This is a solvent free single unit wet curing at room temperature sealant. It is a paste looking substance, can be injected or painted in application. The sealant resists hanging down, can be applied to vertical seam and ceiling seam without dripping. When cured, the sealant forms a rubberlike elastic substance. The product can be used on metal, rubber, wood, cement structure, ceramic and etc. This sealant is for filling gaps (holes, joints, seams and etc.), performing adhesion and sealing.

Product feature

1)Excellent adhesion to various building materials like cement substrate, brick, ceramic brick, metal, wood and etc.

2)Cure at room temperature, neutral, non-toxic, zero pollution and non-erosive.

3)Anti-mould

4)Durable

5)Wear-resisting, tear-resisting and puncture-resisting

6)Excellent weather-resistance and waterproofing

7)No flowing, no sagging, applicable to big gap

Application scope

1)Sanitation facility waterproof

2)Roof and basement waterproof membrane sealing

3)Windows, doors and walls sealing, except for glass wall

4)Gap sealing in bridge, tunnel, culvert and water conservancy

5)Joint sealing between roof and drainage ditch

6)Seam sealing on running water pipeline

7)Water reservoir, water tank and vertical shaft

8)Concrete building seam sealing

9)Concrete road, bridge, runway seam sealing

Application method

Step1. Clear away dust, oil contamination and water on substrate. Remove any rusting using a metal brush. Use alcohol or acetone if necessary.

Step2. Shape the nozzle to fit the application location, manually or air-operatedly apply the sealant to the application location.

Step3. Smoothen and embellish the sealant surface within the surface drying time. Protective tape can be used to prevent nearby area from sealant contamination. Clean up any sealant contamination spot by alcohol dipping cloth.
