At first, water-based paint was not accepted by the public; people were skeptical of this new product, and early on some manufacturers added gasoline, xylene, banana oil and other organic thinners to water-based paint, causing unnecessary trouble.
Basic understanding:
Paint is deeply familiar to consumers and taken for granted, yet many know little about it - even some bosses who sold paint for over ten years don't understand its hazards. Paint can only be occupied one month after application; consumers think it is then non-toxic, but that is wrong - lack of irritating odor only means formaldehyde has dropped to a physiologically acceptable level. The benzene, toluene and free TDI in the curing agent and thinner are still volatilizing; full volatilization takes decades, and these aromatic hydrocarbons greatly affect the intellectual development of infants, children and the unborn, while free TDI is carcinogenic. Developed countries in Europe banned paint long ago.
Development stages:
Water-based paint technology mainly went through three stages:
First generation: acrylic-based, with good water and weather resistance - the main product pushed to market. Drawback: average comprehensive performance, low chemical resistance (e.g., poor alcohol/alkali), lower physical indicators like hardness and abrasion - why many think water-based is inferior.
Second generation: acrylic + water-based PU composite, inheriting first-gen weather resistance and application tolerance while improving hardness, but chemical resistance still low; only a few domestic firms produce it - mid-range.
Third generation: acrylic-modified water-based PU, greatly improving comprehensive performance; pencil hardness above 2H, meeting daily needs; abrasion even exceeding oil paint, with clear advantages in service life and color matching; crucially chemically stable, far better alcohol/alkali resistance - high-end, monopolized by a few domestic and foreign makers.
Although water-based paint has eco and film advantages, single-component still lags two-component oil paint in hardness and heat resistance - e.g., on dining tables and floors its weaknesses show, limiting development.
Until 2008, Japan's No.1 household coating brand Asahi launched the world's first true two-component water-based paint, keeping water-based eco and non-hazardous advantages while, using an eco curing agent, surpassing ordinary two-component oil paint in hardness, heat resistance and clarity.
This launch meant water-based truly began replacing ordinary paint, because it matches or exceeds oil paint in performance, so consumers will stop choosing toxic, long-harmful paint. But this two-component technology is held by only a few like Asahi, and is very expensive, limiting its spread.
Market fake two-component water-based paints are like counterfeit phones - endless knockoffs. Before Asahi launched, some small factories pushed so-called two-component water-based paint that was just modified oil paint: harder, but still full of toxic substances, betraying water-based paint's eco, non-toxic, health-protecting intent.
