Questions buyers ask
Twelve answers, each one short enough to check. Where the honest answer is "it depends", the page says what it depends on instead of quoting a number we cannot hold.
Which products do you make?
Ten models in six families: windscreen adhesives KA518, KA520 and KA530F; sheet metal seam sealer KA540; construction sealants KA340A and KA340B; STP sealant KAM921; PUR wood adhesive KA505; and the K-901 activator and K-801 primer. Every model page carries its full test table.
What is the difference between KA518, KA520 and KA530F?
KA518 is the general-purpose windscreen grade: 3.5 MPa tensile, 320% elongation, 30-minute skin time. KA520 is the high-strength grade for buses and coaches: 4.5 MPa, 450%, 40 minutes. KA530F is the fast grade: 6.5 MPa, 450%, 15 minutes skin time and two-hour positioning.
Do you supply private label?
Yes. Cartridges, sausages and barrels can carry your artwork, and colours can be matched to a sample or RAL reference. Print plates and a physical proof approval come before the bulk run.
What pack formats are available?
310 ml cartridges (12, 20 or 24 per carton), 400 and 600 ml sausages (20 per carton), 200 L / 250 kg barrels, and 5 ml to 1 L cans for activators and primers.
What is the minimum order quantity?
It depends on the pack format and whether a print run is involved, so it is quoted with the order rather than published as a single number. Send the quantity you have in mind and you will get the MOQ for that configuration.
What is the lead time?
Quoted per order, because it depends on pack format, colour and print. The quote states the production time and the shipping time separately so the two are not confused.
Do you send samples?
Sample terms are agreed with the quote — the practical way to test a sealant is a cartridge run in your own application, not a data sheet comparison.
Which standards do you test to?
Tensile strength and elongation to GB/T 528, shear to GB/T 7124, hardness to GB/T 531.1, skin time, sag and extrusion rate to the GB/T 13477 series, volatiles to GB/T 2793, and cure rate to HG/T 4363.
Can you match a colour?
Black, white, grey and beige are standard on the body and construction grades. Other colours are matched to a physical sample or RAL reference, with a match run before the bulk order.
Are you ISO 9001 certified or CE marked?
Both are claimed for the company and the product range. Certificates are supplied on request so the entity and scope can be checked — we do not publish a certificate number we cannot show.
Where do you ship from?
The plant is in Wei County, Hebei. Export orders leave from Hebei; tell us the port you want quoted and the documents your broker requires.
How do I get a price?
Email the model, quantity, pack format, destination and substrate. Prices are quoted per order — the same model costs differently by pack, pallet mix and destination.
