Repair adhesive
Two-component epoxy injection resin used to re-bond hollow tiles: production, filling and labelling under our own control, with every batch recorded against a retained sample.
Company
A formulator, not a reseller
Hongyefeng is a building-materials manufacturer in Jinan, Shandong, China. We produce two-component epoxy for tile hollowing repair and resin grout for tile joints — formulated, filled and labelled under one roof, which is what makes a specification change a conversation rather than a relay.

What we do
Two product lines, one chemistry background
Tile grout
Three resin grout systems — epoxy quartz-sand, gloss epoxy and polyurea — formulated for kitchens, bathrooms and yellowing-sensitive installations, adjustable to your climate within limits.
Why it matters to a buyer
The field is a harder test than the lab
Most resin data sheets are written from a laboratory sample. Ours are backed by retained batch samples and feedback from applicators in the field.
Real substrates
Old cement mortar, gypsum, waterproofing membranes, underfloor heating pipe zones. Each behaves differently, and the formula has to work on all of them.
Real climates
Shandong runs from humid coastal summers to sub-zero winters. A resin that only cures comfortably at 25 °C is not much use in February.
Real accountability
Every batch has a retained sample, so a claim about a shipment is tested rather than argued. If the product is at fault we replace the material — the diagnosis comes first either way.
Quality
How a batch is controlled
Incoming material
Resin and hardener checked against the reference before anything is mixed.
Mixing
Batch recorded with ratio, temperature and operator, so a query can be traced back to a specific run.
Verification
Viscosity and cure behaviour checked against the retained reference for that grade.
Retention
A sample of each batch is kept, so a claim about a shipment can be tested rather than argued.
Documents
Batch certificate issued against the shipment, with technical and safety data available for your broker.
Vendor audits
What we will send, and what we will not claim
If you are qualifying us as a supplier, you need documents rather than marketing copy. Ask and we will send the real ones.
Available on request
Business licence, production and filling capability, current technical data sheet, safety data sheet, and the batch certificate for a shipment you have received.
Not on this site
We do not put certification marks, client logos or capacity figures on a web page. If a document does not exist, we will not print it — and we would rather lose an order than misrepresent one.
