Tackifiers yog cov tshuaj additives tsim los txhim kho kev sib txuas ntawm cov khoom siv los ntawm kev ntub cov khoom sib txuas los ntawm qhov chaw los yog sab hauv diffusion. Raws li lawv cov yam ntxwv solubility, lawv tau muab faib ua dej -raws li thiab roj- raws hom (tom kawg suav nrog ob qho tib si ntsev electrolytes thiab organic compounds). Ntau hom muaj xws li rosin derivatives, roj av resins, thiab terpene resins; Cov no feem ntau muaj qhov hnyav molecular li ntawm 500 txog 2,000 thiab feem ntau muaj nyob hauv lub xeev amorphous, iav. Hauv kev hloov kho asphalt, tackifiers pab txhim kho adhesion thiab modulate elastic modulus, nthuav tawm kev sib raug zoo nrog cov polymers xws li SBS. Hauv cov tshuab roj hmab, lawv yuav tsum tau siv ua ke nrog resorcinol pub rau tsim kom muaj resorcinol-formaldehyde-latex (RFL) bonding system.
Cov khoom lag luam suav nrog ntau pawg, suav nrog hydrocarbon resins thiab rosin esters, nrhiav kev thov hauv thaj chaw kub -melt adhesives, siab- cov nplaum nplaum, thiab kev tsim roj hmab. Biological tackifiers tsim rau cov kua dej drilling muaj qhov siab -kub tsis kam mus txog 180 degree; Qhov sib ntxiv ntawm tsuas yog 0.2% ntawm cov khoom siv ntxiv tuaj yeem nce qhov pom tseeb viscosity mus rau 35 mPa·s. Silicone-raws li tackifiers, thaum ntxiv ntawm qhov concentration ntawm 1.0–2.0%, txhim khu cov adhesion ntawm silicone roj hmab rau substrates xws li hlau, yuav tsum tau ib tug curing kub tshaj 130℃.
