Frequently Asked Questions About Construction Chemical Solutions

The best starting point is your actual application rather than a grade name alone. Please tell us what you produce, such as tile adhesive, wall putty, skim coat, gypsum plaster, EIFS/ETICS, self-leveling mortar, cement-based render, paint, or a daily chemical product.

For a more accurate recommendation, we may also ask about your current brand and grade, formula system, dosage, target performance, local raw materials, and any problems you want to improve. We normally begin with a close benchmark to reduce testing risk, then optimize based on your results.

No. Viscosity is an important reference, but it is not the only factor that determines application performance. Products with a similar viscosity can behave differently in water retention, workability, open time, thickening efficiency, slip resistance, air entrainment, and compatibility with cement, gypsum, fillers, and other additives.

For this reason, when a customer asks for a viscosity such as 100,000 or 200,000 mPa·s, we first confirm the end use. This helps us recommend a grade that is suitable for the performance requirements of the complete formulation.

Yes. We can recommend a comparable product based on your current brand, grade, application, dosage, and performance expectations. The goal is not only to compare a basic specification or price, but to verify that the recommended product works reliably in your own formulation.

A typical replacement process includes product benchmarking, sample evaluation, formula adjustment when needed, a trial order, and verification of commercial production performance. This step-by-step approach helps lower switching risk.

In addition to HPMC, HEMC, and redispersible polymer powder, Kehao Chemical can support related construction chemical requirements including HEC, CMC, PP fiber, PVA, HPS, and other additives used in dry mix mortar and building material systems.

Many customers use our core products as a starting point and later consolidate selected complementary materials with us to simplify purchasing, improve supply coordination, and reduce the number of suppliers they manage.

Our standard packaging is selected to protect powder products during handling, storage, and international transportation. Available options may vary by product and order requirement and can include standard export bags, palletized cargo, and other arrangements subject to confirmation.

If you have specific requirements for bag marking, private labeling, pallet configuration, container loading, or local market compliance, please share them during the quotation stage so we can evaluate the most suitable solution.

Lead time depends on the product grade, ordered quantity, production schedule, packaging requirement, and shipping arrangement. We confirm the expected production and delivery schedule in the formal quotation or order confirmation.

For ongoing customers, we also support supply planning based on historical purchasing rhythm, monthly consumption, available inventory, goods in transit, and shipping time. The objective is to begin the next order discussion before a supply gap becomes urgent.

Depending on the product and destination, we can provide the standard commercial and quality documents required for the order process, such as product specifications, Certificate of Analysis, Safety Data Sheet, packing list, commercial invoice, and shipping-related documentation.

Please provide your destination country, import requirements, and any required document format before order confirmation. Our export team will review the request and confirm the documents that can be arranged for your shipment.

Batch consistency is a central part of our supply approach. Our manufacturing side is responsible for production, quality control, product development, and technical support, while our export team manages overseas communication and delivery coordination.

For new projects, we encourage a structured process of sample validation, trial order, bulk-use verification, and continued batch performance review. This gives customers the opportunity to confirm that the product is stable not only in a laboratory sample but also in regular production use.

We do not treat an unsuccessful test as the automatic end of a project. Our team will first identify the specific performance gap and review the relevant conditions, including formula details, dosage, raw materials, application method, comparison product, and expected target.

For standard applications, our sales team can provide initial selection support. For complex formulations, special performance requirements, repeated testing issues, or strategic replacement projects, our technical team can join the discussion to evaluate adjusted grades or a revised recommendation.
