Best Price Polysulfide Sealant to The U. S.

I
Q:What are the matters needing attention about two-component polysulfide sealant?
A:A component for the white paste, B component for bottled liquid curing agent, (for the convenience of contractor requirements for paint, color box alone, the joining together of A group).When using the B component all packed into A liquid components inside, according to the requirements of construction of color into the paint, rapidly and stir until evenly. With a spatula mixed good sealant stay put into the construction site. Flooding and water contact after 48 hours.
1, team B liquid to all in A component, or will affect the curing time and colloidal. The sealant evenly preparation should be finished as soon as possible (for) two hours) to avoid paste solidification (construction) after curing can no longer cause waste.
2, construction installation interface to clean and dry otherwise affect the bond sealant.
3, within 48 hours after the completion of the engineering to avoid water the rain.

Q:What's the construction method of two-component polysulfide sealant?
A:
1. Sealed surface treatment: before construction to remove oil on the surface of the glued, attachments, dust and other sundry, guarantee the glued surface dry, level off, in order to prevent the bad bonding.
2. Fill the backing material: according to the requirements of design, to the seam filling the backing material, then use a two-component polysulfide sealant. 
3. Besmear bottom coating liquid: design requires the use of bottom coating fluid engineering, or sealing of the submerged for a long time, need touched bottom liquid besmear to brush in glued on the surface, dry film.
4. The configuration of the sealant: according to the instructions given mixture ratio, uniform mixing of two components, can be used. whether machine mixing or manual mixed, should be uniform color and no color difference. With mixed should prevent bubbles, a two-component polysulfide sealant should prevent bubbles into, compaction, fill seal.

Q:What are the performance characteristics of two-component polysulfide sealant?
A:The following are the performance characteristics of two-component polysulfide sealant:
1, good weather resistance, durability, use for a long time not cracks.
2, the sealed components have fully stable adhesion and durable adhesion, concrete in water have long-term adhesion.
3, water vapor transmittance is extremely low, a two-component polysulfide sealant has very good waterproof function.
4, against fungi, bacteria resistance.
5, good construction work, a two-component polysulfide sealant can be a very good fill into the seam.
6, do not produce pollution for the sealing structure, no corrosion, a two-component polysulfide sealant is harmless to the human body.
 



 
IV
Q:What is the using range of two-component polysulfide sealant?
A: Waterproof polysulfide sealant is suitable for joint seal of long-term immersion construction, and coagulation and adhesive performance is good, such as: waterproof joints under, airport runway, water pollution and sewage pool, underground engineering, large-scale water conservancy projects adopt polysulfide sealant.

Q:What is the classification of two-component polysulfide sealant?
A:
A, according to the liquidity can be divided into the droop type (N) and self-leveling type (L) two types.
B, according to the displacement capacity can be divided into 25, 20 two levels.
C, according to the tensile modulus can be divided into high modulus (HM) and the low level of modulus (LM) two levels:
The first type is two-component polysulfide sealant of prolapse, appearance is fine and uniform paste or viscous body, suitable for all kinds of cement building distortion seam, regardless of deformation cracks of the building is standing seam, sewn or sewing, are applicable, the sulfur seal was painted on the structure of the vertical seam or sew later, there will be no sealant is flowing from the construction joint fall off phenomenon, but just stick to the top.
The second is two-component polysulfide sealant of self-leveling type, appearance is the liquid glue with water form, like water, can flow in the deformation cracks, is rare, it is only applicable to the cement building deformation seam sewn, flow resistance, after its proportional ratio, filling and directly to the yard, can flow into the building deformation joint, in the construction of the rift, building plane with self-leveling type two-component sealant can save time and effort.
 
 
 


VI
Q: What are the performance of the complexes of two-component polysulfide sealant?
A:Building polysulfide sealant of not droop type, high elongation, low modulus is rubber high elastomer after completely cured. Mix: master agent (A) : curing agent = 100 (B) : 10 (quality, standard conditions), the changes with seasons, regional temperature. Available curing agent usage, how to adjust the length of the applicable period, changes in the B component range between 8 and 12.
