Silicone sealants for construction projects that must not fail.
Custom silicone sealant manufacturer. We supply neutral, acetic, structural and weatherproof sealants for facade, glazing and general building applications.
Seven grades across five categories
All grades are manufactured on site. Selection is by cure chemistry and joint type; where the joint conditions are known, we will confirm the grade against substrate, movement and exposure.

K-200
Multi-Purpose Weatherproof Sealant
K-300

Eight stages, photographed on our own line
Everything from polymer intake to the loaded container happens inside one site in Shunde. No stage is subcontracted, so a batch record can be traced from the raw-material delivery to the container it left in.
Raw materials
Incoming polymer, filler and additive deliveries are logged against the batch sheet before they are released to production.
Weighing and feeding
Components are weighed and charged in the sequence set by the formulation.
Mixing and kneading
The compound is mixed to the batch sheet. Cycle length follows the formulation, not the line speed.
Bulk filling
Finished compound is transferred to bulk containers for ageing and release.
Quality control
Each batch is released by the on-site laboratory against its specification before it can be packed. The batch record is retained.
Cartridge filling
Cartridges are filled, capped and labelled on the automatic line.
Warehousing
Released stock is held by grade and batch number, so a repeat order can be matched to the original run.
Container loading
Palletised and loaded at our own dock. Loading photographs are supplied with the shipping documents.
The paperwork, as issued
These are the documents we hold, reproduced without retouching. The reference number, validity and named holder are printed on each one; open a document to read it in full.

Selection by cure system
Acetic-cure grades achieve the fastest adhesion to glass. Neutral-cure grades are non-corrosive and are specified for metal, masonry and sanitary applications. Full technical data is published in the TDS for each grade.
| Grade | Category | Cure system | Typical joint |
|---|---|---|---|
| K-100 | Acetic | Acetic, one-part | Glazing, mirrors, general building joints |
| K-200 | Weatherproofing | Neutral, one-part | Large glass curtain walls, exterior joints |
| K-300 | Weatherproofing | Neutral, one-part | Sealing, bonding and repair work |
| K-400 | Weatherproofing | Neutral, one-part | Glazing, metal and masonry, interior and exterior |
| K-500 | Structural | Neutral, one-part | Curtain wall structural bonding, skylights, stone |
| K-600 | Anti-mildew | Neutral, sanitary | Bathrooms, kitchens, permanently damp joints |
| K-700 | PU foam | Moisture cure | Frame gaps, service penetrations, cavities |
From enquiry to repeat supply
Joint review
Provide substrate, joint dimensions and exposure conditions. We return a recommended grade and its datasheet.
Sample
Trial cartridges, labelled as proposed, for evaluation by your applicator.
Trial order
A reduced first shipment to clear customs and obtain site approval before volume commitment.
Repeat supply
Batch records are retained, so subsequent shipments can be matched to the approved sample.
Before you send an enquiry
Questions not covered here can be sent directly to our technical team; enquiries are answered within one business day.
What is the minimum order quantity?
MOQ is determined by grade and packaging and is confirmed on the quotation. A single figure would not be accurate across the range; provide the grade, cartridge size and destination and we will state the minimum in writing.
How long does production take?
15–30 days depending on grade and packaging, calculated from artwork approval for private-label orders. Container loading is arranged at the plant.
Can samples be supplied before ordering?
Yes. Trial cartridges are supplied with the proposed label so that your applicator can evaluate the product and its cure behaviour.
Do you manufacture under our own brand?
Yes. OEM and private label are standard. You supply artwork; we print, fill and pack to it, and retain the batch record for repeat orders.
Which certifications can you provide?
ISO 9001, CE, SGS and BV, together with MSDS and TDS for every grade. Where a tender requires a specific report, we will confirm its availability before you submit.
Submit the joint details, and we will return a specification.
Substrate, joint dimensions, exposure and destination are sufficient to begin. Enquiries are answered within one business day.
